It's called a hasp? I had to cut the one on my trailer because I... umm... locked the keys to my truck in the trailer at VIR Anyway I called the company that makes it, Flexco but they don't sell retail and couldn't' give me the info I needed to find it locally. Please help! It;s the part the cam door handle goes into. The image to the far right.

I'm guessing the chain is more to hold the door shut, thus someone falling out (based on the permanantly depressed button on the door handle) rather than prevent some on from coming in.
BZZZZZ!!! We had the correct bit and stripped the bit! It wouldn't budge. So I have to replace the $7 part...
